TLDR; Started the game at 44% battery, ended with 25% after half an hour. Above says it all really. Doesn't seem to be well optimized, Macbook Pro 14 M1 got decently warm, could feel it through the keyboard. I've played more than a few games on this machine and this is by far too simple of a game to run this hot. The game itself is simple and to the point but perhaps knowing a mistake has been made before reaching the end of the game would be helpful to others. Also labels or a guide for what the buttons do would also be nice. All in all this was what I was looking for but I wasn't expecting to have to connect to my charger after one match. It doesn't deserve anything less than 3 stars but the battery drain is unacceptable.

I would prefer it had a good help feature instead of having to wait till you realize you made an incorrect choice!

Besides a lack of explanation of the colors and other screen activity, this app constantly runs my CPU at over 60% causing the fans to come on and my keyoard to get hot. This occurs even when when I'm just staring at the numbers and there's no game activity.It was so bad that I had to uninstall this program.I read their privacy policy and while they say they don't collect any indentifable info from you, they use 3rd party services that may be collecting your identifable information. It feels like there's a free-for-all going on inside my macbook.

Immediately as you load in, it asks you to turn on notifications and buy their premium version. Then, once you finish a puzzle, it tries to force an email from your Apple account to everyone in your contact list. On top of that, it then creates twice as many pop-ups asking you to buy the premium version. Do not install this app!
